To all whom it may concern:

Beit known that I, CiiiN'ioN W. DiciciN; soN, a resident of La Crosse,in the county ofLa Crosse and State of l/Visconsin, have inventedcertain new and useful Improvef ments in Agricultural Implements, ofwhich the following is a full,lclear, and exact description. b

T he invention relates to tractor drawn implements and more particularlyto that type in which operating mechanism is d i'iven by a tractionwheel. l

It has heretofore been proposed to provide plow-shifting mechanism whichwas operatively connected to a traction-wheel. This traction-wheelusually served as a. carrying-wheel for the frame and served to sustaina part of theload or frame, or was so disposed or connected to the frameso that it'could perforrnthe function of a carrying-wheel. The loadimposed upon this traction-wheel was relied .upon for thenecessaryvtraction which would cause the wheel to vrotate in travelingover the ground, so thatit would drive the plow-shifting or raisingmechanism. In tractor-plows, particularly in those in which plowsharesare separately raised or lowered,a numberof adjustments are necessary toinsureA operation .ofthe plowshare at the desired depth, to causetheirbottoms to he disposed 'at the correct transverse and longitudinalangles. In some soils, greater pressure is necessary upon thetraction-wheel than in others in order to obtain the requisite tractionto operate the plow-shifting mechanism. If, howevcr, attempt is made toadjust the traction-'wheel relatively to the frame, variation of'theposition-'lof the plow-supporting,Y

structure or frange relatively tothe ground wouldvtip the rrame' :mdmresffondingly disturb the relation ofthe plowshares, particularly withrespect to transverse and longitudinal inclination, so that-readiustment would be vnecessary throughout the plow-to rectify thevvariation resulting` from adjustment between the frame and this tractionwheel.

One object of the invention is to provide an improved implement in'whichvariable pressure may be exerted upon the tractionwhecl withoutdisturbing the --supporting structure and without necessitating any ofthe readjustments which would be necessary when an adjustable connectionbetween the combinedv supporting and traction-wheel is made to attainthe necessary traction. This object is attained by 'providing atractionwheel which does ,not serve as a supporting wheel and-which 'iscapable of adjustment to. viary its traction without disturbinr theposition of the plow supporting struc ture relatively to the ground andby interposing the traction wheel lin .the draft device, so that it willcause the traction-Wheel to be pressed with the desired force into theground. By mounting the tractionwheel in the draft-device, and byadjusting the draft-connection to the frameor at the tractor, thepressure of the traction-wheel upon the ground maybe readily variedindependently of the wheels which support and carry the supportingframe. The. other objects and advantages of the invention will bemanifestfro'm the detail descri tion of a plow embodying anexemplification of the invention.

lnthe drawings: Figure l is a plan of a plow embodying the invention,parts being broken away. Fig. 2- isa vertical section taken on line .2-2of I"ig.'1. Fig. 3 is a perspective of the improved draftdevice with thetraction-Wheel connected thereto and the mechanism for driving theplowshifting mechanism from said wheel. Fig. 4 is a detail of one of theindividual plowshifting mechanisms. Fig. 5 is a side eleyation, partsbeing broken away and shown in section, illustrating the controllingdevice 'for the clutch for driving the plowshifting, mechanism.

The invention is illustrated as applied to a plow which comprises asupporting frame which consists of a front cross-bar 10, i1 side bar 1l,a diagonal bar-12, and longitudinal bars 14, all secured together :inany suitable manner. This frame is sustained by a land-wheel 15 disposedin the frame and onan axle which'isnimted in suitable bearings on theframe', a side furrow-wheel 16, and a trail wheel 1T. These wheels maybe connected to the frame in any suitable manner, as well understood inthe art. A series of plow-beams 18 each carrying,r a plow-share 19,*arearranged in diagonal succession, so that the plowshares will operatesuccessively in the ground to turn each furrow slice into the furrow cutby the plowsliare in advance thereof. Each" plowbeain 18 is pivotallyconnected, as at 20, to

a4 suitable adjustablecoupling 21, which is secured to the diagonalframe-bar 12. A cross-shaft 22 is mounted in suitable bearings 23 on theframe and serves to operate the plow-shifting linkages; ,Each plowbeainis supported by a gage-wheel 24 which sustains a standard 25 which isslidably and rotatably held in a bracket 26 secured to the beam. Alinkage is provided for raising and lowering each beam. Each of theselinkages comprises an arm 27 pivoted on shaft 22, a link 28, having vacurved front end pivoted, as at 29, to arm 27, a bellcrank lever 30, towhich the rear end of 'link 28 is pivoted, as at 31, and which ispivoted at 32 to the plow-beam 18 and a ink 33 pivoted togage-wheel-standard 25 and to the arm 34 of lever 30. Each plowshiftinglinkage is operated to raise its beam by a tooth 35, which is secured torotate with shaft 22 and is adapted to engage a dog 36, which ispivoted, as at 37, to arm 27 When the plow is raised, the linkage isadapted to pass into dead-center relation, as indicated by dotted linesin Fig. 4, and will then be automatically locked in position to hold thebeam arid plowl raised. The curved end of link 28 is adapted to strikethe tail 39 of dog 36 to disengage the dog from tooth 35 when the beamhas been raised. During eachvoperation o'f shaft 22, it will make onecomplete revolution ,as hereinafter more fully set forth. The depth towhich the-plow will be lowered is controlled by a screw 40 which ismounted in a bracket 41 on link 28 and is adapted to engage a slide 42on link 28, and a. link 43which is pivoted toslide 42, asat 44, and toarm 27 as at 45. A cam 46, rigid with shaft 22, is adapt ed to engage anabutment 47 `on bracketl 41 to shift the linkage across its deadcenterand release the plow-beam so it will drop until arrested by the stop 42.A stud 48 on dog 36 is adapted to ride on a guide 49 to hold dog 36 outof the path of tooth 35 when the linkage is being operated to lower theplows.

The teeth 35 for operating the dogs 36 of the plow-shifting mechanisms,respectively, are set in rotative succession on shaft 22, so that thelinkages will be operated .to successivel y raise the plows out of theground on a line transverse to thefline of travel. Cams 46, forreleasing the linkages to lower the plowshares, are also Vset inrotative succession on the shaft 22 so that the plows will besuccessively lowered into the ground on a line transverse to the line ofdraft. lt the linkages are inthe position shown by full lines in Fi 4,one complete revolution of shaft 22 will cause the teeth' thereon tosuccessively engage the dogs 36 until all of the linkages areautomatically locked to hold the plows raised. If the linkages are inthe position shown'by dotted lines in Fig. 4, D.

complete revolution of shaft 22 will cause the cams 46 to successivelystrike abutments 47 and operate the linkages to release the plolwsharesand cause them to drop into the soi Each arm 27 is formed with a socket27, which is adapted to receive a rod or lever 27, whereby the plowshifting mechanism may be operated by hand if desired.

The mechanism for driving the shaft 22 comprises a traction-Wheel 50which is secured to an axle 51 which is journaled in bearings 52 and 53.These bearings are secured to the draft-frame 54 which is pivotallyconnected to the plow-supporting frame by bolts 55, which are adaptedAto pass through either of a series of holes 56 in ang1e-bars 57 whichare secured' to the front rail 10 of the supporting frame by bolts 58.An angle-bar 59 1s secured to `the front of the draft frame and adraft-link G0 is hitched to said bar by a bolt 361. Bar 59 is providedwith 'a series of holes 62, so that the vdraft-link 'may be adjustedlaterally.

By adjustment of the bolts v in holes 56, the pressure exertedupontraction-wheel 50 by the draft frame may be varied as desired. Forexample, by` lowering bolts 55 without changing the point of hitch tothe tractor, there will be more vdown-pull on the draftframe 54 andgreater pressure of the Wheel 50 upon the ground. In some cases,adjustment of the connection to the draft-frame will suffice forpractical purposes. 1n' some instances, however, for exam le where Softspots are encountered, it mig t be desirablel to provide an additionaladjustment-where# by the pressure may be varied .more quicklyv andwithout stopping the operation of the plow and for this purpose, 'fthedraft-frame 54 is made up of an outer bail 63 to which the clevis-bar 59is secured and an inner bail 64 to which the bearings 52 and 58 are seA`cured, bolts 55 extending through the sides of beth members of the frameto pivotally connect them to the vertical Clovis-bars 59. A level' 65 ispivoted, as at 66, to a bracket 67 which is secured to the clevis-bar59, as at G8. A link 69 is pivoted at 70 to a lug 71, which is securedto the front of draft-ineinber G4 and to lever-"65. Lever 65 is providedwith a lock-bolt 72 for engaging a segmental rack 73 on the bracket 67.This lever 65 and link 9`se`rve vas an adjustable connection between"thcdraftanembers for relatively lowering that m'mber in which thetraction-wheel 5() is mount-editi force'said wheel onto the ground.vithfijiorrgpr less pressure' as desired.` By mounting thistraction-wheel in the draft-frame, the pres sure of the wheel may beadjusted so that for this traction-wheel without raising or lowering anypart of the low-supporting structure, so that no readJustment of theframe or the plows is necessary when the pressure of the traction wheelis varied.

Traction-wheel 50 is utilized to drive shaft 22 to shift the linkagesfor operating the plow-beams. The drivingconnection between the axle 51of traction-wheel 50 and shaft 22 comprises a sprocket wheel 75 which isloose on said axle, a sprocket wheel 7 7 which is mounted on a shortshaft 8l approximately co-aXial with the point about which thedraft-device swings (bolts 55), a sprocket chain 76A between sprocketwheels 75, 77, a sprocket wheel 78 rotating with sprocket 77, a sprocketwheel 79 fixed to shaft 22 and a. sprocket chain 80 between sprocketwheels 78v and 79. Shaft 81 is mounted in brackets 82 which are securedto the' lfront rail l0 of the supporting frame. By providing adriving-connection including the rotating sprocket wheels 77 and 78disposed substantially in co-axial relation with the pivotal connectionbetween the draft frame 54 and the supporting frame, adjustment of thetraction-wheel or pivotal movement of the draft-frame. will notmaterially effect the operation of the chain 76. A ratchet wheel 84 issecured to rotate constantly with axle 51 and a dog 85 pivotallyconnected, as at 86, to an arm 87, is adapted to engage the ratchet andto be operated thereby to cause arm 87, which is fixedly connected tosprocket 53, to be rotated. Ratchet 84 and dcg 85 serve as a clutch foroperating the driving-connection for shaft 22. The operation of thisclutch is controlled by the rod 88 which is slidably mounted in guides89 on the draft-member 64 and is normally held in the path of anabutment 90 on dog 85 by a' spring 91. Rod 88 is suitably connected to alever 92 which is pivoted as at 93 to a bracket 94 on the draft-memberG4 and a wire or cable 95 extends from the upper end of this lever to apoint within convenient rea-ch of the operator on the tractor.

In operation, a pull upon cable 95 will Withdraw rod 88 from the path ofdog 85, so that the latter will drop into engagement with a ratchet 84and be operated thereby one complete revolution at the end of which, rod88 will have been restored to the path of abutment 90 on dog 85 todisengage the dog from the ratchet. A complete revolution of dog 85-will impart one revolution to sprocket wheel 75, which, by means of thesprocket chain connection, will drive shaft 22 one complete revolution.If the plows are lowered in the ground, the beam-shifting connectionswill be in position shown by full lines in Fig. 4 and teeth 85 on shaft22 will operate the dogs 86 to raise the plowbeams until the linkageswill be automatically locked in raised position. If the plowand in whichthe traction-wheel for driving,

said shaft or mechanism is connected to the draft appliance. Theinvention also exemplifies an improved tractor plow in which atraction-wheel frcm which power is derived for driving the beam-shiftingmechanism may be adjusted to vary its pressure upon the groundindependent y of the supoorting-wheels and frame. It also exemplifiesmechanism in which the traction-wheel for driving the beam shiftingmechanism is disposed in or connected to the draft-connection or frame.It also exemplifies a draft-frame to which the traction-wheel isconnected which may have its connection and supporting frame adjusted.It also exemplifies a machine in which the pressure o f g.;.

the traction-wheel may be quickly adjusted by means ofa lever which maybe locked in different positions. It also exemplifies a machine in whichthe pressure regulating means for the traction-wheel is disposed closeto the tractor where the operator on the tractor may readily make thenecessary adjustment from the tractor. By supporting the traction-wheelin the draft-device, the necessity of providing an additional frame forthe traction wheel is obviated.

lVhile the invention has been illustrated as embodied in a plow, it willbe understood that certain broad features thereof may be utilized inother agricultural implements in which the power derived from atraction-wheel is employed to drive a shaft or mechanism on thecarrying-frame.

The invention is not to be understood as restricted to the details setforth, since these may be modified within the scope of the appendedclaims without departing from the spirit and scope of the invention.

Having thus described the invention, what I claim as new and desire tosecure by Letters Patent, is:
